<p>A gear (1) for a hydraulic piston machine having at least one gear pairing comprising two gearwheels (6, 10). It is desirable to be able to operate such a gear with relatively high efficiency also with a hydraulic machine that operates with water or a corresponding fluid as hydraulic fluid. For that purpose, the first (6) of the two gearwheels is made of a metal and the second (10) of the two gearwheels consists, at least at its surface, of a friction-reducing plastics material.</p> |
